The conversion of abandoned butted well salt cavities into underground storage facilities holds immense significance for safeguarding energy security and improving the ecological environment. A significant barrier to reconstruction these old is limited comprehension their complete morphology, caused by residue coverage. three-dimensional seismic techniques excel in identifying complex geological structures but have a understanding cavity thus forward simulation method utilized study response patterns. Based on 3D data, logging measured shape parameters from Yexian mine region Henan Province, China, model observation system were established. characteristics cavern model, encompassing five distinct morphological attributes such as spacing, diameter, height, sediment horizontal connection channel thoroughly investigated. findings show that roof exhibits distinctive “two peaks sandwiching strong valley” feature, with positions valley remaining aligned serving reliable indicator cavity’s top surface. width waveform an exponential amplification effect relative width. residue’s surface presents “upward-opening arc” wave peak downward shift diminishes height increases. This forms circular feature reflection waveform, always located upper half this waveform. channel’s bottom surfaces exhibit contrasting patterns, position aligning trough shifting brine cavern, residue, mainly chaotic reflections. There are identification top, connecting simulation. research provide valuable guidance morphology real based data accelerating construction facilities.

An in-depth investigation of the adsorption and diffusion mechanism hydrogen in low-rank coals is great significance for optimizing technical path geological storage improving efficiency storage. Two kinds coal samples with a low metamorphic degree from Foran Coal Mine Sihe were used as adsorbents, molecular structure determined experimentally, H2 molecules was analyzed atomic level based on numerical simulation. It found that aliphatic carbon mainly links aromatic ring form branched chain exists an ring, side chain, or bridging carbon, lower deterioration coal, longer length alkane structure. The present polybenzene can provide more effective sites enhance by High specific surface area porosity will samples, while presence oxygen-containing functional groups strengthen interaction between microporous H2. These findings theoretical support application

Abstract The Germans energy transition (Energiewende) is a long-term strategy aimed at transforming the country's system to achieve carbon neutrality by 2045. This centered on three key pillars: improving efficiency, accelerating deployment of renewable energy, and ensuring stable supply during shift away from fossil fuels. Over past decades, Germany has made significant progress in expanding sources, particularly wind solar power, which now account for substantial share its electricity generation. Russia-Ukraine war posed challenges German transition, disrupting natural gas imports leading short-term measures such as temporary reactivation coal-fired power plants. geopolitical highlighted need accelerate adoption develop robust storage solutions ensure security. By 2030, aims install least 20 GW capacity annually 12 manage intermittency power. Despite these challenges, crisis also created opportunities. sharp rise prices incentivized investment efficiency measures. actively seeking alternative partnerships, strengthening cooperation with China technology exploring hydrogen collaborations African nations. These strategic shifts are expected play crucial role shaping next phase Energiewende. paper examines evolving opportunities focusing aspects expansion solutions, policy adjustments needed navigate changing landscape.
